Surf ac an s are w idely applied in he process of he prepara ion f or heir special s ruc ure consis ing of a hydrophilic and a hy drophobic group. T he dispersing m echanism s of surf ac an s and he dispersing func io n in he prepara io n are presen ed m ainly. T he principles of som e m e hods fo r nanoma erials are in roduced , such as empla e- direc ed sy n hesis based on several or ganiz ed surf ac an assem blies, he u se of micr oem lusion , hydro herm al syn hesis, sol- gel m e hod, and so on. Finally, he la es repor s in his f ields ar e summarized in order o give an ex pec a ion o surfac an sf u ure applica ion .
